For thispurpose, and according to my 105 namedmay be moved, is, according to my inven presentinvention, I-provide aneccentrically or tion capable of being moved into and out of the cam.shaped scroll g5 (F lgspl and 'revolubly "operative position'by hand.mounted in connection with the framing 4, T1 1 scroll is'shown mountedaway from or inde- Referring to the accompanying drawings, 1 a 4 I Fig.1 shows parts involved in my said'in've'ntion pendently 01' th pp ev i eScroll 11 with the Said domng quadrant tobe revolved catch ismoved byhand into the disengaged posiand partial revolution of the pinion 40.

named is driven by gearing such as at 26 (Fig. 5) in gear with wheel 27.This wheel 27 is fixed on the end of the front bottom roller and isdriven through the usual well-known gearing from the driving shaft ofthe machine.

A pivoted finger-piece 28 is capable of engaging the grooves of thescroll by means of a projecting part at 29. This finger-piece is held incontact therewith by means of a spring 36 (Fig. 1) referred to later, sothat the fingerpiece may be disengaged by hand when necessary.

The piece 28 is pivoted at 28 by passing between the sides of a slottedportion in part 31 and connected by pin thereto, said part 31 beingattached to a shaft 31 in manner indicated, which shaft is attached to aslotted arm 32, the latter being in connection by link 33 with a lever34 pivoted at 35 on the frame 4. One end of the lever 34 is connected bythe helical spring 36 already referred to, and only partly indicated infull, to the frame 4, while an' opposite end mark 37 of the lever 34 isin link connection with a handle or pivoted lever 38 (Figs. 1, 2 and 5)which lever replaces the ordinary handle employed for moving thequadrant 10 as already referred to.

This lever 38 is slotted at the right-hand end in Fig. 1 in which slotis placed a flattened projection 39 which is pinned to the lever named,as indicated in Fig. 2. One end of a plate spring 38 is shown attachedto the projection 39, and which spring bears against the lever 38, (seealso Fig. 2). The projection 39 is part of the shaft carrying the usualpinion now marked 40, and which is in gear with the teeth 24 of thequadrant 10, as already explained.

It will be obvious that under the conditions named and shown, when thelever 38 is moved outwardly on its pin attachment to the projection 39,asindicated by broken lines in Fig. 2 the pinion 40 can be partiallyrevolved by the movement up-and-down of the lever 38, and in a directionvertically to the plane of Fig. 2. This movement, when the lever namedis so positioned as stated, may be utilized to ease the quadrant orslightly raise the same, when it is desired to disengage the catch 21from the stop 20, for dofling purposes. V I

For the production of a bunch of yarn on each yarn carrier, however, thelever 38 is capable of being moved into an aperture, here of flaredform, at 41 provided in a link 42 connecting the said lever 38 withlever 34; (see full lines for lever 38 in Fig. 2)

When so connected, the lever 38 aforesaid becomes automatically underthe control of the scroll 25, or the slight up-and-down movement of thelever 32, due to the action of the revolving scroll upon piece 28, willresult in an alternating This movement, through the quadrant 10, andchain 8 will give the small traverse of the ring rails necessary to formthe bunch of yarn 2 beforenamed.

. The conditions necessary for this bunching motion to be operating,require the disconnection of the heart-shaped cam 14, for which purpose,

a clutch at 43 (Fig. 5) between gearing 17 and bevel 15 is capable ofbeing disengaged by operation of a pivoted handle 44 in-connection withthe upper part of the, clutch 43., The depression of the handle 44, inthe example given, allows a drop-catch 45 to pass in front of aprojection 46 on the handle 44. This catch 45 temporarily holds thehandle 44 in the depressed position named.

In this way, the heart-shaped cam .14 ceases to function during thebunching operation. For adjusting the cam 14 so that the bunch may becorrectly positioned, on the yarn carrier, gearing 47 is movable by ahandle 48 which moves round a cam 49 on the shaft 50 until a pawl 51falls into gear with the cam illustrated (see Figs. 5 and 7). The pawl51 is pivoted on the frame of the machine.

After a bunching operation is completed, and the ordinary building-up ofthe yarn on the yarn carrier is desired to be commenced, the clutch 43may be automatically put into gear again, for which purpose, accordingto what is illustrated, the projecting end 37 of the lever 34 isarranged to press down a part 52 of the drop-catch 45 (Fig. 6 moreparticularly), and at an opposite side of a pivot 53 therefor. The part52 is here a stud (with a squared end below) in screw thread connectionwith a part 45 of the catch 45, the height of the upper end of 52 thusbeing adjustable. The part 45 named is attached to a shaft 53 (see Fig.5) the latter being attached to the drop-catch 45. Contact betweenlever-end37 and part or stop 52, tends to turn shaft 53 and to turn thecatch 45 about the pivot 53. Said catch 45 is thus lifted clear of thehandleprojection 46 before-named, and the handle 44 is then able tolift, such as under the action of a spring 54 shown in Fig. 5.

The extra amount of" depression on the part of the end 37 of lever 34,is attained by the scroll 25 being provided with an extended groovedpart 55, so thatwhen the finger-piece 28 is engaged by said extendedpart, it is pushed away fromthe axis of the scroll named to a greaterextent than before. This increased movement gives the result alreadyreferred to.

It is obvious that the form of the scroll may be adapted to the needsinvolved, and that the intervening mechanism l'employed'may beconsiderably altered or modified to suit the conditions under which thesame. is used. a V r A spring-resisted catch 56 (Figs. 1, 3 and 4) isshown pivoted at 57 to a bracket 58 attached to the frame 4, whichbracket also supports pinion 40. .For said spring resistance a platespring 57* is shown in Fig. 1 passing behind an upright part 56 fromapartof catch 56 projecting Ion the left of pivot 57. (See also Fig. 4.)r This catch56 Operates to hold up the catch21 in the position saidlever pushes against a stop 59 on the catch 56, and turns the latter onpivot 57 so that said catch 56 is disengaged from catch 21. The latteris then'free to fall by gravity to the position shown in Fig. 1 readyjforabutting against the stop 20 on the quadrant 10. In practice, the

weighted and extended end 21 of the catch 21 would come against a stopbelow it on part of .the'framing 4, to limit the extent of fall of thecatch 21 aforesaid. This happens, as already inferred, when the bunchingoperation ceases.
